Fish tail or more likely shell?

[Red Benjamin]

Hi all,

Maybe this find is past identification due to erosion, but i thought it may be of interest to others

Length is around 8 inches 

I can see similar lines to the shell / tail feature on the right of the 'solid' part..

Wondering if anyone has any idea what it might be? is it two separate fossils perhaps?

All the best

Looks like a bivalve shell with some mineral veining around it.

Ah hah thank you Tony, there's a multidude of crushed shells around this zone of the beach, i was confused by the 'solid' object at the bottom (maybe part of a Plagiostoma gigantea?) combining with the fan shell almost coming out of it...

I'll go for bivalve too, with what looks like some fossilised wood at the bottom. (Edit: I think the wood is smooth shell, maybe Plagiostoma as you say.)

 

A good candidate at that size is Antiquilima succincta which is generally rather a scarce one.

Thank you Viera the ribs are quite distinctive now it has been mentioned

The bit to the left with finer ribs is probably from a different species.

Thank you muchly Tarquin!

have found this and yes it is very similar with ribs and growth marks
